Abstract
A system and method include acquisition of positron emission tomography data of an object while a radiation source moves within the object, determination of a plurality of locations within the object, each of the plurality of locations associated with a respective time at which the radiation source was located at the location, determination of a respective time period associated with each of the plurality of locations, determination, for each of the determined time periods, of a frame of the positron emission tomography data associated with the determined time period, and, for each frame of the positron emission tomography data, generation of an image based on the frame and on the location associated with the time period associated with the frame.
Claims20
A system comprising:
- an imaging device to:
- acquire positron emission tomography data associated with an object including a moving radiation source;
- a processing system to:
- determine a plurality of locations within the object, each of the plurality of locations associated with a respective time at which the radiation source was located at the location, wherein the plurality of locations are determined without user input of the plurality of locations;
- determine a respective time period associated with each of the plurality of locations;
- determine, for each of the determined time periods, a frame of the positron emission tomography data associated with the determined time period;
- for each frame of the positron emission tomography data, generate an image based on the frame and on the location associated with the time period associated with the frame;
- and
- display the images.
A method comprising:
- injecting a radiation source into an object;
- acquiring positron emission tomography data of the object while the radiation source moves within the object;
- determining a plurality of locations within the object, each of the plurality of locations associated with a respective time at which the radiation source was located at the location;
- determining a respective time period associated with each of the plurality of locations;
- determining, for each of the determined time periods, a frame of the positron emission tomography data associated with the determined time period;
- and
- for each frame of the positron emission tomography data, generating an image based on the frame and on the location associated with the time period associated with the frame.
A computing system comprising:
- a memory storing processor-executable process steps;
- a processing unit to execute the processor-executable process steps to:
- acquire positron emission tomography data of an object while a radiation source moves within the object;
- determine a plurality of locations within the object, each of the plurality of locations associated with a respective time at which the radiation source was located at the location;
- determine a respective time period associated with each of the plurality of locations;
- determine, for each of the determined time periods, a frame of the positron emission tomography data associated with the determined time period;
- and
- for each frame of the positron emission tomography data, generate an image based on the frame and on the location associated with the time period associated with the frame.
